Have you already tried this:
Cleaning the low level sender contacts (front of the filler neck). That sorted mine out.

Quote from: davehghave you changed the plugs recently?? strange question i know but the wire for the coolant buzzer/sensor connects the the loom down the back of the power steering and aircon pumps, its a pain to find but if its not attached then the buzzer will go off intermitantly.

I hate to resurface such an old thread, but I\'ve tried finding this wire for ages!
Got the coolant ligh and buzzer problem thats just started after i got the plugs cleaned and filter changed. Mecchie did fiddle around with the plugs for ages so I immediately assumed he\'d knocked a wire.
Search brought out this thread.

Is this the same wire mentioned above that can only be seen from undeneath the car?
The only wire I can find that isn\'t connected to anything is white and brown coloured, and it had some insulating tape left on...

Can\'t believe how loud that damn sound is!!!

Cheers.

I think this may be my problem: one of those wires. I had trouble identifying which wire went to the oil pressure sensor, and which to the temp sensor. Maybe i have these muddle up. I alsi have a spare one because i have dropped my air con - but maybe this is the wrong one! So i have three cables that may all be connected up to the wrong thing! Is there anyone who can identify the colours of temp sender, oil pressure and air con?

DRAGON · August 18, 2006, 07:00:48 PM

from Memory (maybe wrong) water is yellow and white. oil press is grey and red. Not sure on air-con

Cheers Ross, i\'ll check it out.

nikp · August 18, 2006, 07:43:23 PM

Bugger! Broke the cable (currently) going to the temp sensor - that was white and brown!?! Took the cable off the oil pressure switch and couldn\'t tell what colour it was cos it is sheathed in insulating tape - so in the morning will stick it on the temp sensor and see if the buzzer goes off then.

Okay mate found this post over on rx7club too.

So you put the white/brown wire onto the temp sensor and it didnt work?
Damn guess ima have to locate another wire then.

Can you tell me exactly where the temp sensor is, even after reading the posts i\'m a bit blind :2Confused

btw. Are you able to get at these cables from above w/o removing the elbow, or are you looking from underneath?

I\'ll reply again in a bit. Guests have jsut arrived :Hammer

Thanks

again from memory (maybe wrong, but unlikely

the brown and white goes through the loom and joins to the black water level sender on the termostat housing.

nikp · August 18, 2006, 08:08:33 PM

Ok, i found out that there\'s a black plug and white plug (behind the power steering pump/air con compressor) that are meant to be connected together, which weren\'t - but are now!

But i still have the alarm, which i guess i would do since i broke the white and brown wire, so still can\'t proove that everything is hunky dory!

Fancy a trip to Bristol Ross!?

nikp · August 18, 2006, 08:15:44 PM

So, hang on - if i have white/brown connected to the temperature sendor sensor by the oil pressure switch, is that wrong? I think it is, isn\'t it!?

grrr....bloody electrics!

DRAGON · August 18, 2006, 08:31:05 PM

yellow and white goes to water sender near oil pressure sender.
Brown and white connects to spade connector in the loom, which then goes onto the water level sender on the thermostat.
call me if you want I\'m still at the workshop.

nikp · August 18, 2006, 08:36:29 PM

Cheers - I won;t at the mo, as like i said, i\'ve broken the brown and white cable, so until i fix that (tomorrow morning), there\'s no point in me continuing.

Thanks for the offer - may cal in the morning though (if you\'re there!

Zee · August 18, 2006, 08:51:13 PM

Sweet lads that\'s narrowed it down for me.
Your memory seems spot on Ross :King

Gettin a bit dark out so gonna have a butchers in the morning.
Brown/White wire to spade in loom...

Zee · August 19, 2006, 03:55:06 PM

Okay I\'ve tried to find the connecter but no luck at all!

Here\'s a quick pic of where I\'m looking, you can see the white/brown wire pretty much in the middle.

Thanks
